TOC ZFI2/ZFI3 Operations Manual -1-
General Description The TOCZFI3 is a three channel wireless Zoom Focus Iris control system. The system can be used on most broadcast or cinema lenses. The TOCZFI3 includes a hand held controller/transmitter, rechargeable battery (not pictured), three lens drive motors (TOC ZFI2 includes two motors), three channel capable receiver, three universal gear sets (TOC ZFI2 includes two gear sets), and battery charger.
1. Setup The TOC is provided with various gears to fit almost any broadcast or cinema lens. Select the proper gear pitch for the proper lens ring. The gears can also be switched to either side of the motors if needed. Warning: If you are using the TOC with a servo powered lens, make absolutely sure that the lens servo for the function you’re trying to control is always deactivated, otherwise the lens servos can end up fighting the TOC motors resulting in severe damage to either the lens or the TOC system.
After the motors have been mounted on the rods, secure the gears against the proper lens rings and tighten the dovetail clamps. Mount your TOC receiver and attach the antenna. First plug the lens motors into TOC receiver according to their function (yellow to yellow, zoom to zoom, etc) Then plug power from camera into the TOC receiver (red to red).
The lens motors will then move to the position at which the controllers are set. Note: If you turn off power to the receiver, it will store the calibration set in the last use. As long as you don’t move the motors or lens, the calibration will be valid. If you have to move the motors and lens from their last position, recalibrate. Basic Operation The TOC has a touch screen that will allow for easy menu navigation. Most operation will be done from this screen.
1. Home Screen From the Home Screen, you can monitor the current lens positions as well as enter the setup screens for Zoom, Iris, and focus. You can also enter the Control, Calibrate, Setup, and System menu screens. From this screen tap “Open Iris” to fully open iris. Tap the button again to return the iris motor to the location of the iris slider. There is also a “Set” button that will recalibrate the zoom toggle in case it starts to drift. 2.
is not a defect or a problem. The bar graph is just displaying the “relative” input force on the toggle, and the zoom motor reaches its maximum speed well before the indicator reaches the end of the bar, so you’ll get equal speed control in both directions regardless of the indicator’s maximum excursion. Speed is adjusted the same way, and will control how quick the motor responds to the Toggle. Press the “ ” button in the top left corner of the screen to return to the Home Screen. 3.
4. Focus Setup Menu From the Focus Setup screen, you can set the focus motor and focus knob limits, reverse motor and knob response direction, as well as adjust smoothing. To set a limit, simply move the knob to where you want the limit, and tap the “set limit” button. Once a limit is set, the “Set Limit” button will then read “Clear Limit”. Tap this button to clear the limit. Motor and knob response direction is changed by selecting the “Dir+” button located under either “Motor” or “Knob”.
For manual calibration, tap the motor you wish to calibrate listed under “Manual” to enter the manual calibrate screen (as shown to the left). Move the iris slider to the center position as indicated on the screen – a center mark will appear and further instructions will be shown on the screen. The slider will now be used to run the motor until the first end point of the lens is reached.
communication between the hand unit and receiver. This mode is only used when making firmware upgrades, and requires a LEMO to serial cable. “Motor Backlash” is used to compensate for backlash in the lens rings. Not all lenses have backlash, and this is only necessary if the lens “lurches” when changing direction. Backlash setting should be kept to a minimum unless necessary. 7.
B) -General Malfunctions: The most common cause of malfunctions is ‘hot swapping’ the motors (i.e., plugging the motors (yellow plug) into the receiver while it is already connected to its power source (red plug) – Solution = Don’t hot swap the motors – unplug and re-plug the power to the receiver (red plug) – in other words, always make sure the motors is plugged in before the power. C) -Auto Calibrate Mode not functioning properly: Solution 1 = Using an AC adapter? If so, try switching to battery power.
lens servos can end up fighting the TOC motors resulting in severe damage to either the lens or the TOC system. Please be aware that some “full auto” modes may override the lens servo switches.
